add_hash(hash: int) int

Adds the vector into the running hash.

add_hash(hash: int, threshold: float) int

Adds the vector into the running hash.

add_to_cell(i: int, value: float)

These next functions add to an existing value. i.e. foo.set_x(foo.get_x() + value) These are useful to reduce overhead in scripting languages:

add_x(value: float)
add_y(value: float)
add_z(value: float)
almost_equal(other: LVecBase3d) bool

Returns true if two vectors are memberwise equal within a default tolerance based on the numeric type.

almost_equal(other: LVecBase3d, threshold: float) bool

Returns true if two vectors are memberwise equal within a specified tolerance.

assign(copy: LVecBase3d) LVecBase3d
assign(fill_value: float) LVecBase3d
compare_to(other: LVecBase3d) int

This flavor of compare_to uses a default threshold value based on the numeric type.

compare_to(other: LVecBase3d, threshold: float) int

Sorts vectors lexicographically, componentwise. Returns a number less than 0 if this vector sorts before the other one, greater than zero if it sorts after, 0 if they are equivalent (within the indicated tolerance).

componentwise_mult(other: LVecBase3d)
cross(other: LVecBase3d) LVecBase3d
cross_into(other: LVecBase3d)
dot(other: LVecBase3d) float
fill(fill_value: float)

Sets each element of the vector to the indicated fill_value. This is particularly useful for initializing to zero.

fmax(other: LVecBase3d) LVecBase3d
fmin(other: LVecBase3d) LVecBase3d
generate_hash(hashgen: ChecksumHashGenerator)

Adds the vector to the indicated hash generator.

generate_hash(hashgen: ChecksumHashGenerator, threshold: float)

Adds the vector to the indicated hash generator.

get_cell(i: int) float
static get_class_type() TypeHandle
get_data()

Returns the address of the first of the three data elements in the vector. The remaining elements occupy the next positions consecutively in memory.

get_hash() int

Returns a suitable hash for phash_map.

get_hash(threshold: float) int

Returns a suitable hash for phash_map.

static get_num_components() int
get_standardized_hpr() LVecBase3d

Try to un-spin the hpr to a standard form. Like all standards, someone decides between many arbitrary possible standards. This function assumes that 0 and 360 are the same, as is 720 and -360. Also 180 and -180 are the same. Another example is -90 and 270. Each element will be in the range -180.0 to 179.99999. The original usage of this function is for human readable output.

It doesn’t work so well for asserting that foo_hpr is roughly equal to bar_hpr. Try using LQuaternionf.is_same_direction() for that. See Also: get_standardized_rotation, LQuaternion::is_same_direction

get_x() float
get_xy() LVecBase2d

Returns a 2-component vector that shares just the first two components of this vector.

get_xz() LVecBase2d

Returns a 2-component vector that shares just the first and last components of this vector.

get_y() float
get_yz() LVecBase2d

Returns a 2-component vector that shares just the last two components of this vector.

get_z() float
is_nan() bool

Returns true if any component of the vector is not-a-number, false otherwise.

length() float

Returns the length of the vector, by the Pythagorean theorem.

length_squared() float

Returns the square of the vector’s length, cheap and easy.

normalize() bool

Normalizes the vector in place. Returns true if the vector was normalized, false if it was a zero-length vector.

normalized() LVecBase3d

Normalizes the vector and returns the normalized vector as a copy. If the vector was a zero-length vector, a zero length vector will be returned.

operator_new(size: int)
output(out: ostream)
project(onto: LVecBase3d) LVecBase3d

Returns a new vector representing the projection of this vector onto another one. The resulting vector will be a scalar multiple of onto.

read_datagram(source: DatagramIterator)

Reads the vector from the Datagram using get_stdfloat().

read_datagram_fixed(source: DatagramIterator)

Reads the vector from the Datagram using get_float32() or get_float64(). See write_datagram_fixed().

set(x: float, y: float, z: float)
set_cell(i: int, value: float)
set_x(value: float)
set_y(value: float)
set_z(value: float)
static size() int
static unit_x() LVecBase3d

Returns a unit X vector.

static unit_y() LVecBase3d

Returns a unit Y vector.

static unit_z() LVecBase3d

Returns a unit Z vector.

write_datagram(destination: Datagram)

Writes the vector to the Datagram using add_stdfloat(). This is appropriate when you want to write the vector using the standard width setting, especially when you are writing a bam file.

write_datagram_fixed(destination: Datagram)

Writes the vector to the Datagram using add_float32() or add_float64(), depending on the type of floats in the vector, regardless of the setting of Datagram.set_stdfloat_double(). This is appropriate when you want to write a fixed-width value to the datagram, especially when you are not writing a bam file.

property x float
property xy LVecBase2d
